Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod holding fixture and a method for forming a scaffold, which can securely hold and fix a rod by a simple operation.

[0002]

2. Description of the Related Art In order to prevent a danger zone such as a construction site from being divided by a person or a bicycle, two or more lower portions are widened in order to prevent the danger zone from entering the danger zone. Are arranged, and the parallel barricades are connected by a long rod such as a single tube to form a barricade.

[0003] By the way, in order to connect the barricade body and the bar body, conventionally, a method of binding the bar body to the barricade body with a rope, a wire, or the like, or a bar body holding body using a tightening action of a bolt nut is used. The method of holding a rod between the body and the barricade body has been adopted, but both methods require work time and complicate the work of assembling the barricade. Furthermore, labor costs are incurred due to the work time.

On the other hand, when a plurality of rods are connected in a crossed or parallel state to form a scaffold, one person supports the rods, and the other person holds the rods with a scaffolding rod holder. A work mode of fixing is adopted. This is because it is difficult to operate the rod-holding brackets for the scaffolds that connect the rods together. (Because it is necessary to securely hold and fix the rods for safety, it is inevitable to turn the bolts and nuts. This is because a troublesome operation such as a moving operation is required.) This is because it is impossible for one person to operate the scaffolding bar holding fixture while supporting the bar. Therefore, this method has a problem that labor cost is required for two persons.

Further, when a plurality of rods are connected to form a frame such as a snow enclosure, a method of tying the rods with a rope, a wire, or the like has been conventionally used, but in this case also, a long working time is required. In addition, if the work takes time when working at a high place, the danger of the work increases correspondingly, which is a problem.

[0006] In addition, rod-holding metal fittings and the like used when forming a scaffold, such as rod-holding metal fittings that require particularly high security, have a structure for firmly maintaining the state of holding the rod. Is required.

The present invention solves the above problems,
A rod-holding metal fitting and a scaffold forming method that can be attached and detached smoothly and reliably by a very simple operation, and that can hold the rod extremely firmly and have excellent practicality and workability. It is intended to provide.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described with reference to the drawings.

The first embodiment will be described with reference to FIGS.

In the first embodiment, the holding half 3 is provided on a base 2 provided with a rod supporting portion 1, and the holding half 3 is mounted on a rod 4 abutting against the rod supporting portion 1. A rod holding fixture A for holding and fixing the rod 4 by being fitted therein, the base end of the holding half 3 being pivotally connected to one end of the base 2, and the distal end of the holding half 3. A stopper 5 is provided on the other end of the base 2, a shaft 18 is provided laterally on the other end of the base 2, and a stopper operating body 7 is provided.
The stopper operation body 7 is pivotally attached to the other end of the base 2 by inserting the shaft rod 18 into the elongated hole 19, and the stopper operation body 7 can be engaged with the locking body 5. A stopper 8 is provided, and when the stopper operating body 7 is rotated and the stopper operating body 7 is slid upward with respect to the shaft rod 18 to increase the amount of protrusion from the other end of the base 2, A state in which the locking portion 8 is configured to be removably lockable to the locking body 5, and the stopper operating body 7 is held in a state where the locking portion 8 is locked to the locking body 5. By rotating the stopper operation body 7 with respect to the shaft rod 18 downward, the stopper operation body 7 can be pivotally mounted on the other end portion of the base 2 in an attached state. When the rod body 4 is held by the rod supporting portion 1 of the base 2 and the holding half 3, The topper operating body 7 is rotatably disposed in a state of being attached to the other end portion of the base 2, and the stopper operating body 7 is slid with respect to the shaft rod 18 by the rotation of the stopper operating body 7, and Is locked to a shaft locking portion 20 provided at one end of the elongated hole 19, so that the locking portion 8 cannot be disengaged from the locking body 5 and the rod 4 can be held and fixed. It is related to the rod holding metal fitting A which has been made.

An overhanging portion 21 is provided in the elongated hole 19, and the stopper operating body 7 is rotatably disposed in a state of being attached to the other end portion of the base 2, and the stopper operating body 7 is rotated by the rotation of the stopper operating body 7. The operating body 7 is slid with respect to the shaft 18, and the shaft 18 is provided at one end of the elongated hole 19 with the shaft locking portion 20.
At the time of locking, the shaft rod 18 gets over the riding-over portion 21 and is locked to the shaft rod locking portion 20.

Therefore, in a state where the rod 4 is held and fixed to the rod holding member A, when the holding half 3 is to be rotated upward, the holding portion 5 and the engaging member 5 are attached to the holding half 3. The stopper operating body 7 connected via the stopper 8 attempts to slide upward along the shaft 18, but at this time, the shaft 18 has to climb over the crossover 21. Therefore, unless the force exceeding the overcoming force acts on the holding half 3, the state in which the holding half 3 holds the rod 4 is not released.

The crossover portion 21 is formed by forming the long hole 19 into a long hole 19 that is bent in the middle, and the bent portion is set and provided in the crossover portion 21.

The shape of the elongated hole 19 is such that the rod 4
And a bent portion is provided in the middle of the slanted elongated hole 19, and a portion above the bent portion is further separated from the rod body 4 than the slanted elongated hole portion (horizontal elongated hole). ), And the tip of the oblong hole is set in the shaft rod engaging portion 20.

The stopper operating body 7 is formed in a U-shape in a plan sectional view, and a horizontal rod 9 is provided between the opposed protruding pieces 6, 6, and the horizontal rod 9 is set to the locking portion 8. ing.

Further, the elongated holes 19 are provided in the opposing loose protrusions 6.

The other end of the base 2 is provided with a fitting portion 15 to which the stopper operating body 7 is fitted when the stopper operating body 7 is attached to the other end of the base 2. Therefore, the operation of attaching the stopper operating body 7 to the other end of the base 2 is
The rotation is guided by the fitted engagement between the stopper operating body 7 and the fitted portion 15, and the last rotation operation of the stopper operating body 7, which is the most important when holding the rod 4, is performed. It can be done reliably.

The fitting portion 15 is configured such that the stopper operating body 7 and the locking portion 8 fitted to the fitting portion 15 do not protrude from the right and left sides of the base 2 in a side view.

The locking member 5 provided on the holding half 3 is formed in the shape of a tongue, and the horizontal rod 9 is pressed and locked on the locking member 5 in the shape of the tongue, thereby locking the locking member. The locking between the locking portion 5 and the locking portion 8 is achieved.

The locking body 5 is formed by adjusting the upward degree of the tongue-shaped locking body 5 up and down so that the rod body support portion 1 of the base body 2 and the holding half body 3 hold the rod body 4. A holding force increasing / decreasing mechanism 22 for increasing / decreasing a holding force is also provided. Specifically, if the upward degree of the locking body 5 is adjusted upward, the stopper operating body 7 is slid downward and the shaft 18 is positioned at the shaft locking portion 20 in the elongated hole 19. In this state, the locking portion 8 of the stopper operating body 7 strongly presses the locking body 5, so that the holding half 3 inevitably has a stronger pressing force on the rod 4, and the rod 4 is firmly held. It will be held and fixed. Also, if the upward degree of the locking body 5 is adjusted downward, the force by which the holding half 3 fixes the rod 4 becomes weak.

At the tip of the stopper operating body 7, there is provided a finger hook 16 which can be hooked by a finger when rotating the stopper 7 attached to the other end of the base 2. The stopper operating body 7 is provided so as to be set in a shape that allows the distal end portion to warp.

Further, the tip of the locking body 5 of the holding half 3 is configured to be bent upward, and the rebound portion releases the locking of the locking portion 8 to the locking body 5. And a function as a finger hook when the holding half 3 is rotated.

Although the illustrated rod support 1 is formed in an arc shape which substantially matches the outer peripheral shape of the rod 4, the rod support 1 and the rod 4 are taken into consideration in consideration of the coefficient of friction between the rod 4 and the rod 4. The body support 1 may be formed in a jagged shape. The whole is made of metal.

Hereinafter, the method of using the first embodiment will be described in detail.

First, the rod 4 is placed on the rod supporting portion 1, and the holding half 3 pivotally attached to one end of the base 2 is rotated to hold the rod 4 on the rod 4. The body 3 is fitted.

Subsequently, the stopper operating body 7 attached to the base 2 is rotated upward, and the stopper operating body 7 is slid upward to thereby reduce the amount of protrusion of the other end of the base 2. Enlarge the locking portion 8 (lateral rod 9) so that it can be disengaged from the locking body 5, and lock the locking portion 8 to the locking body 5 (see FIG. 3). In this state, the shaft 18 is located below the long hole 19.

Subsequently, the stopper operating body 7 is rotated downward, and the stopper operating body 7 is slid downward, thereby reducing the amount of protrusion of the other end of the base 2 and moving the locking portion 8 into the engagement position. The locking portion 8 is engaged with the locking body 5 so as to be disengageable from the locking body 5 (see FIG. 3). In this state, the shaft rod 18 is located halfway in the elongated hole 19 and immediately before the riding section 21.

Subsequently, the stopper operating body 7 is further rotated downward, so that the shaft 18 in the elongated hole 19 of the stopper operating body 7 rides over the riding-over section 21 and the shaft 18 is engaged with the shaft. Part 20
(See FIG. 4). By the operation of the stopper operating body 7, the locking portion 8 fitted and locked on the locking body 5 strongly presses the locking body 5 (that is, the holding half 3).
Presses the rod 4. ), The pressing of the locking portion 8 disables the holding half 3 from rotating, and the work of fixing the rod 4 is completed.

In this way, once the holding half 3 is made unrotatable by the stopper operating body 7, for example,
Even if a force for lifting the rod 4 suddenly is applied and the holding half 3 is rotated upward by the rod 4, the holding half 3 is locked by the locking body 5 of the holding half 3. Although the locking portion 8 attempts to pull the stopper operating body 7 upward, the state in which the shaft 18 in the elongated hole 19 of the stopper operating body 7 is locked by the shaft locking portion 20 is maintained. The stopper operating body 7 cannot slide and move upward unless the shaft rod 18 in the hole 19 gets over the riding-over section 21. Therefore, the locking portion 8 of the stopper operating body 7 The locked state is maintained, and the holding and fixing action of the rod body 4 is maintained.

When releasing the holding of the rod 4, the stopper operating body 7 is rotated upward so that the shaft rod 18 in the elongated hole 19 gets over the riding section 21. Thereby, the pressing and locking between the locking portion 8 and the locking body 5 is released.

According to the experiment, the rod holding fixture A having the above-described structure was used.
It was confirmed that even when a load of 800 kg or more was applied to the rod 4, the stopper operating body 7 did not rotate, and the holding and fixing action of the rod 4 was maintained.

Since the first embodiment is configured as described above,
The rod 4 can be smoothly fixed to the rod holder A by a simple operation such as rotating the holding half 3 and the stopper operating body 7 or sliding the stopper operating body 7. Moreover, the rod holding member is excellent in practicality and workability, in which the rod 4 can be easily and smoothly removed simply by rotating or sliding the stopper operating body 7.

The stopper operating body 7 may rotate or slide unless the shaft rod 18 locked in the shaft locking section 20 in the elongated hole 19 gets over the riding section 21. The rod 4 fixed to this rod holding fixture A
Even if a load is applied to the rod, the fixing will not be released if the shaft rod 18 does not move beyond the riding-over section 21, so that the rod 4 can hold and fix the rod 4 firmly and is excellent in practicality and safety. It becomes a body holding bracket.

Further, since the holding half 3 can be integrally provided with components such as the locking member 5, the bar holding metal fitting A is manufactured by a simple manufacturing means such as pressing from a metal plate. This is a highly productive rod-holding bracket that can be used.

Further, the width of the stopper operating body 7 is made narrower than the lateral width of the attached base 2 in side view, so that the stopper operating body 7 and the locking portion 8 do not project from the left and right sides of the base 2. Therefore, it is difficult for another rod or foot to be accidentally hooked on the stopper operating body 7, and the pressing and locking between the locking portion 8 and the locking body 5 is released, so that the rod holding metal A
Thus, the rod 4 can be securely fixed to the rod holding fixture A without the rod 4 fixed to the rod being detached.

The second embodiment will be described with reference to FIG.

In the second embodiment, a connecting portion (not shown) is provided on the base 2 of the rod holding member A used in the first embodiment, and the two rod holding members A are connected at the connecting portion. When the scaffolds are formed by connecting the rods 4 and connecting them in parallel or in parallel to form a scaffold, the rod holding fixtures A and A are configured to be rotatable and non-rotatable. As described above, the two rods 4 are brought into an intersecting state, and the rods 4 are temporarily connected to each other by the two rod holding members A, and then the rods 4 are temporarily connected. Are connected by a known scaffolding rod holding fixture, and thereafter, from the rods 4 connected by this scaffolding rod holding fixture, the two connected rod holders A.A
, And the rod body 4
Are connected to form a scaffold.

In the connecting portion, a hole is provided in the bottom flat portion of each of the bases 2, 2 and a screw body such as a bolt is inserted into the hole by aligning the positions of the holes of the two bases 2, 2. When a bolt or nut is loosened, one rod holding member A can freely rotate with respect to the other rod holding member A when the bolt and nut are loosened. On the other hand, when the bolts and nuts are tightened, one rod holding member A cannot rotate with respect to the other rod holding member A.

It should be noted that even if a load of about 800 kgf is applied to the bar 4 held by the bar holding fittings A, the rod 4 should not be detached from the bar holding fittings A. Set.

The method of attaching and detaching the rods 4 to and from the rod holding fixtures A is the same as in the first embodiment.

Therefore, in the second embodiment, as in the first embodiment, the two rods 4 can be smoothly mounted and operated by a very simple operation.
The rods 4 can be detached and the rods 4 can be connected and fixed by adjusting the rotation angle of the rod holding brackets A, A according to the mounting angle of the two rods 4. When forming a scaffold by connecting with one another, the rod 4 is temporarily connected by operating the rod holding metal fittings A and A with the other hand while supporting the rod 4 with one hand, and then The rod 4 thus temporarily connected is operated by both hands using a well-known scaffold rod holding fixture for scaffolding, so that the rod 4 can be easily connected by one person. Scaffold formation method.

Further, since the force for holding the rod 4 of the rod holding metal A is strong, the rod holding metal A for temporary connection is used as a rod holding metal for a scaffold as it is. This is a scaffold formation method with excellent practicality.

It should be noted that the number of the rod holding members A to be connected is not limited to two, but may be, for example, 3 depending on the number of rods 4 to be connected.
It may be one.

The two or more rod holding members A, A, which are connected to each other, may be used, for example, when a plurality of rods 4 are connected in parallel or in an intersecting state to form an assembly such as a snow enclosure. For example, the connecting portion provided on the bottom of the base 2
The two bar holding members A, A are connected, and one of the two connected bar holding members A, A is fixed to the bar 4 erected from the ground. , A bar 4 parallel to the ground
Is pivotally operated so as to be able to be fixed by the other rod holding metal member A, and the rod member 4 is fixed to the rod member holding metal member A. At the intersection of the rods, the rods 4 can be fixed to the rod holding brackets A to form a snow enclosure.

That is, the two rod holding members A and A used in the second embodiment are two rod holding members A.
The connecting angle of A can be adjusted to a desired angle, and the parallel rods 4 and the crossed rods 4 can be fixed to the rod holding brackets A, A, respectively. Also, one-touch operation can be performed by rotating or sliding the stopper operating body 7. For example, when a scaffold or a snow fence is to be formed, a conventional well-known scaffolding bar holding metal fitting, a rope or a wire may be used. The assembly work can be performed much more smoothly and the work time can be significantly reduced compared to the method of binding, and the work can be done safely even when working at a high place, making it possible to work safely ,
It is a rod holding bracket with excellent workability and low work cost.

The rest is the same as in the first embodiment.

The connecting portion is not limited to a structure in which it is fastened with bolts and nuts. For example, the connecting portion may be axle-fitted with rivets or the like. May be formed separately from the one provided with, and these may be engaged to be rotatable and non-rotatable.
